Michail Antonio netted a first-half winner against the Black Cats - and duly followed up it up with a very original celebration indeed.
And Brady was happy to start the weekend so well - with West Ham up to fifth after the Sunderland win.
She took to Twitter to express her delight, a feeling no doubt mirrored by the Hammers faithful:
Great win today - 5th in the table, lovely start to the weekend.— Lady Brady (@karren_brady) February 27, 2016
West Ham face Tottenham on Wednesday night following their Sunderland win and can hold outside hopes of finishing in the top four.
Manchester City are currently in poor form and so are Manchester United in behind them. What a great way a top-four place would be to say goodbye to Upton Park.
Even a top-six finish, though, would represent a very good season for Slaven Bilic's men.
